Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a hoisting device for installing prefabricated staircases. Background Technology

[0002] With the continuous promotion of prefabricated buildings and the increasing requirements for assembly rates, the proportion of prefabricated staircases used in high-rise buildings is gradually increasing. Prefabricated staircases require specialized hoisting equipment during installation to be moved from their original location to a pre-reserved location within the building using a crane.

[0003] For example, the patent document with application number 202123437821.6 discloses a hoisting device for installing prefabricated stairs. This application relates to a hoisting device for installing prefabricated stairs, which includes a crane, a hoisting plate and a hoisting ring. The hoisting ring is set on the hoisting plate, and a hoisting beam is set on the hoisting plate. A slider is slidably sleeved on the hoisting beam along the length direction of the hoisting beam. At least two sliders are set. A hoisting rope is set on the slider. A hook is set on the end of the hoisting rope away from the slider. A limiting member for limiting the position of the slider is set on the slider. The lifting ring is attached to the hook on the crane to fix the lifting plate to the crane. First, the distance between the two sliders is adjusted according to the length of the prefabricated staircase to be lifted. Then, the position of the slider is limited by the limiting component. Next, the hook is attached to the embedded part on the prefabricated staircase. The prefabricated staircase is lifted to the designated position by the crane for installation. The hook can be fixed to the four corners of the prefabricated staircase by adjusting the distance between the lifting ropes at both ends of the prefabricated staircase. The operation is simple, increases the stability of the lifting, and prevents safety accidents. However, if the prefabricated staircase shakes during transportation, the impact force generated by the shaking will affect the stability of the lifting equipment and may also damage the lifting equipment.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a hoisting device for installing prefabricated stairs. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, a hoisting device for installing prefabricated stairs includes a lifting beam 1. A lifting ring 101 is provided in the middle of the upper surface of the lifting beam 1, and guide grooves 102 are provided on both sides of the upper surface of the lifting beam 1. The advantage of this setting is that the sliding direction of the adjustable slider 2 can be restricted by the setting of the guide grooves 102.

[0023] Furthermore, the inner surface of the guide groove 102 of the rotating rod 3 is slidably equipped with an adjustable slider 2, and the lower end surface of the adjustable slider 2 is provided with a support frame 201. The advantage of this setting is that the position of the lifting device can be adjusted according to the size of the staircase by setting the adjustable slider 2.

[0024] Furthermore, damping shock absorbers 202 are fixedly installed on both sides of the rotating rod 3 and the support frame 201. A sliding frame 204 is provided at one end of the damping shock absorber 202 near the support frame 201, and a rotating seat 205 is provided on the lower surface of the sliding frame 204. The advantage of this arrangement is that, through the setting of the damping shock absorber 202, the shaking of the precast stairs can be reduced during the process of the hook 403 lifting the precast stairs, so as to avoid damage to the equipment caused by the impact of the shaking of the precast stairs.

[0025] Furthermore, the upper and lower end surfaces of the rotating rod 3 and the support frame 201 of the rotating rod 3 are provided with limiting grooves 203, and the limiting grooves 203 and the sliding frame 204 are configured to slide. The advantage of this configuration is that the sliding direction of the sliding frame 204 can be restricted by the limiting grooves 203, thereby reducing the wear of the sliding frame 204 and improving the service life of the sliding frame 204.

[0026] like Figures 3-4As shown, a rotating rod 3 is rotatably mounted on the inner surface of the rotating seat 205, and an adjusting head 301 is provided on the left side surface of the rotating rod 3. The advantage of this setting is that, by setting the rotating rod 3, the angle of the support plate 4 can be adjusted by rotating the rod 3 when the prefabricated staircase is too long, thereby reducing the stress generated when the suspension rope 402 pulls the prefabricated staircase.

[0027] Furthermore, a support block 303 is provided on the left side surface of the rotating seat 205 of the rotating rod 3, and an insert rod 302 is slidably installed through the surface of the support block 303. A compression spring 304 is provided on the lower outer surface of the insert rod 302, and a pull ring 305 is provided on the lower surface of the insert rod 302. The insert rod 302 and the adjusting head 301 are slidably connected. The advantage of this setting is that, by setting the compression spring 304, after the angle of the support plate 4 is adjusted by using the rotating rod 3, the insert rod 302 can be driven into the interior of the adjusting head 301 by resetting to limit and fix the rotating rod 3.

[0028] Furthermore, a support plate 4 is provided on the outer surface of the rotating rod 3, and a winch 401 is installed on the inner surface of the support plate 4. A hoisting rope 402 is provided on the outer surface of the winch 401, and a hook 403 is installed at the end of the hoisting rope 402. This configuration is an existing device and will not be described in detail.

[0029] Working Principle: When using this prefabricated staircase installation hoisting device, firstly, depending on the size of the prefabricated staircase to be hoisted, the spacing is controlled by sliding the adjustable slider 2 along the guide groove 102. If the length of the guide groove 102 is insufficient, the angle can be adjusted by rotating the support plate 4 through the rotating rod 3. Then, the compression spring 304 is used to compress and reset the lifting rod 302, which is inserted into the adjusting head 301 to fix the rotating rod 3, thus adjusting the support block 303 to reduce the stress generated during hoisting. After adjustment, the prefabricated staircase is lifted using the hook 403. If the prefabricated staircase shakes during hoisting, the impact force generated by the shaking can be buffered by the sliding frame 204 sliding along the limiting groove 203 on the surface of the support frame 201 and pressing the damping shock absorber 202, thereby ensuring the stability of the prefabricated staircase. This is the working principle of this prefabricated staircase installation hoisting device.
